I have some information on why this is happening, Cole.
If you are the contractor, your employer or client can use their QuickBooks Online account to send you an invite to fill out your Form W-9. You can reach out to your employer and let him resend the invite or link. If you already have a QuickBooks Self-Employed account, ask them to send the invite to the email address you use to sign in to your account. Otherwise, you can sign up for an account. You can create a limited QuickBooks Self-Employed account just for your forms.
Please know that It's your employer or client's responsibility to give you your 1099-MISC. If you don't want to create a QuickBooks Self-Employed account, reach out to them to get a copy.
To know more about how you can fill out and update your W9, check out this article for more information: Fill Out A W-9 and View Your 1099-MISC in QuickBooks Self-Employed.
You can always get back to us if you have any questions about 1099. I'm always right here to help.
